For draining a flow through cuvette:
note: Whilst using a 1.8 ml flow cell, order numbers 035 025 (glass) and 035 044 (quartz), the sample
can only be drained in
Bi-Directional mode.
If you wish to drain the flow through cell between sample measurements in
Independent or
Segmented modes it is recommended that you use a 80µl flow through cell; order numbers 035 045
(glass) and 035 047 (quartz).
Automatic Sip on/off
When
Automatic Sip is set to On the measurement sequence is followed automatically once the
sample measurement is started. This is dependent on both the instrument and sipper mode with
various prompts and warnings displayed, as necessary. In general, the instrument controls will produce
the same effect as a press of the accessory pushbutton.
note: Measuring calibration standards using the sipper pump can only be performed when
Automatic Sip is set to On.
With
Automatic Sip set to off the sipper will go through the sample handling process step-by-step
with each press of the accessory push button.
In
Kinetics mode when Auto Log is set to On readings will not be saved or printed until the sample
has been drained. In all other modes the result is printed before the drain cycle.
Calibrating the Sipper Pump
From the
Accessory Settings menu press Calibrate. The following screen is displayed:
Offer a sample to the inlet tube in the sipper probe.
Press
Start, the sipper pump will start to operate. View the sample being taken up through the
polythene tube to the flow-through cuvette. Ensure the sample fills the chamber of the flow-through
cuvette, press
Stop when the sample is just visible in the outlet tube. Further adjustment to the
sample uptake can be made using the + / - (uptake volume) buttons. When the correct level is
achieved press the
Done button.
A prompt for air segmentation is given. If separation of samples is not required pressing the
Done
button will skip this process and a drain cycle will be performed and the instrument will return to the
Accessory Settings menu.
